The Lake Michigan mercury mass balance model, LM2-Mercury, which was calibrated to a comprehensive data set collected from Lake Michigan during 1994–1995, was applied to predict long-term total mercury concentrations in lake water for different mer

This study revisits and updates the Lake Michigan Mass Balance Project (LMMBP) for polychlorinated biphenyls (PCBs) that was conducted in 1994–1995. This work uses recent concentrations of PCBs in tributary and open lake water, air, and sediment to

LM2-Mercury, a mercury mass balance model, was developed to simulate and evaluate the transport, fate, and biogeochemical transformations of mercury in Lake Michigan. The model simulates total suspended and resuspendable solids (TSRS), dissolved orga

The reactive (fixed) nitrogen (Nr) budget for Lake Michigan was estimated, making use of recent estimates of watershed and atmospheric nitrogen loads. Reactive N is considered to include nitrate, nitrite, ammonium, and organic N. The updated Nr load

The Louisiana continental shelf in the northern Gulf of Mexico experiences bottom water hypoxia in the summer. In this study, we applied a biogeochemical model that simulates dissolved oxygen concentrations on the shelf in response to varying riverin

For more than forty years, the herbicide atrazine has been used on corn crops in the Lake Michigan basin to control weeds. It is usually applied to farm fields in the spring before or after the corn crop emerges. A version of the WASP4 mass balance m

LM3-Eutro is a high-resolution eutrophication model with several improved features lacking in historical Great Lakes models. We calibrated LM3-Eutro using a 2-year (1994–1995) dataset and performed a hindcast simulation from 1976 to 1995 to evaluat

A Lake Michigan Ecosystem Model (LM-Eco) that includes a detailed description of trophic levels and their interactions was developed for Lake Michigan. The LM-Eco model constitutes a first step toward a comprehensive Lake Michigan ecosystem productiv

In present food web bioaccumulation model formulations, the exposure temperature of a food web is typically defined using a single spatial compartment. This essentially assumes that the predator and prey of a food web are exposed to the same environm

The Lake Michigan Mass Balance Project (LMMBP) was a part of the Enhanced Monitoring Plan (EMP) for Lake Michigan ( McCarty et al., 2006 ). PCBs (polychlorinated biphenyls) were one of the targeted pollutants studied in the project. As one of the com
